Percolation? Heat soak? Don't drive during summer??

Ahhhh, yeah. That's the good stuff. I've rarely had that cause much issue. That said, I just hate dealing with wires covered in adhesive so I switched to the non adhesive stuff for long wraps and then use the super 33 to close the ends (or heat shrink, if I can manage).

It really only matters if you plan to unwrap at some point to redo, replace, or reroute. If you're not going to "re" anything in the foreseeable future, then normal tape is fine.

Yea this super 33 is like 8 bucks a roll... for connectors I always use heat shrink connectors, then usually electric tape over them just to be safe..

I imagine like most things of the stuff on this old car.... it will get replaced at some point in the next couple years. Ill most likely get a brand new wiring harness, I only had those 2 spots with open wires, the rest of the wiring harness is actually really nice. Nothing is frayed, no melting of wires, etc. Its just the car carries kids, I want it to be at some point 100% gone through and reliable. My daughter says this is going to be her car when she gets to start driving... by that time hopefully this car is done right? And hello coronet and gts??? Lol
